So you have a situation where even when the original patent holder donated the patent for "the public good," sooner or later, an obnoxious patent troll like IV comes along and turns it into a weapon.
Again: AmEx patented those little numbers on your credit card, and then for the good of the industry and consumer protection donated the patent to a non-profit, who promised not to enforce the patent against banks... and then proceeded to sell the patent to Intellectual Ventures who is now suing banks over it.
